Hell, I wish I could make my car stay at a desired RPM than a desired speed.

Don't some tractors have a simple 'choke cable' type throttle option? Seems you pull it out and twist it to lock the rpm you want. If you step on the throttle, it mechanically disengages some how. Any sod busters reading this ever seen one?

If you come up with one, let me know, I'd be interested, too.

Sounds Perfect; I would like such a device; esp if it would release with the brake as well.

How about a solenoid that locks the cable at X throttle until you release it.

If the servo is vacuum operated, why not hook into a vacuum source, run it to the dash with a regulator and simply "dial in" the desired amount of speed?

You've got An Idea there; but it would dial in the amount of throttle, not speed; PERFECT.

Ofcourse you would have to bypass the control portion of the cruise actuator.

You could the hook it to the brake booster with a check valve that would "Turn off" the cruise when applying the brake.

Damn, I'm full of ideas!

This is a rough draft and the "check valve" may have to be an electric dump valve hooked to the brake switch to work right. Maybe some other members can improve on this idea.

I love the idea of a DIY vacuum actuator system

but here is a $40 electronic throttle lock, disengages cruise by touching the brake

http://www.conrad-anderson.co.uk/cru...rottlelock.htm

they are located in the Uk so i dont know how much shipping would be.
